Emeritus Professor of Mathematics Jerry Janusz presents a survey, step-by-step, of most of the known techniques used in solving Sudoku puzzles and illustrates them with many examples so that the casual solver may learn to complete some of the "hard puzzles" that appear in some newspapers and other publications. He provides twenty-five pages of instruction for beginners to Sudoku puzzle solving and ninety pages for more advanced players.

The book begins with a description of three elementary techniques that will allow the reader to solve "easy" and "medium" Sudoku puzzles. Then more advanced methods that depend on "candidates" are presented. Techniques such as wings, chains, several types of reduction, almost locked sequences and others are introduced as part of the detailed solution of some difficult and diabolical puzzles. Some consideration is given to puzzles with more than one solution.
